摘要

A laser Raman microscope was used to obtain spectra from polytene chromosomes intranscriptionally active salivary gland nuclei of Drosophila melanogaster third-instar larvae. Bands for DNA, nucleosomes, proteins, and nuclear membrane fatty acids were identified in difference spectra generated from 1:1 subtraction of the cytoplasm spectra from nuclear spectra. The presence of bands corresponding to B-
